Dental crowns, also known as "caps," preserve the functionality of damaged teeth. This common dental restoration may be used to protect a cracked tooth, restore functionality of a tooth with excessive decay, or replace a pre-existing crown. It encases a needy tooth with a custom-designed material. Dentists today have a variety of conservative treatment options through which to restore teeth. If possible, these options should be explored and discussed before selecting the full coverage crown.
The predominant material choices for all-ceramic crowns is zirconia or aluminous. They provide a metal-free aesthetic option with a number of benefits.
By eliminating the need for the supportive metal core, an aesthetic all-ceramic crown can be created with a reduced thickness of material. This makes it a more favorable treatment choice in areas with limited space. Additionally, the elimination of the metal core allows for light transmission through the porcelain for better optical, life-like properties and a higher level of aesthetics.
All-ceramic materials continue to evolve in strength and durability, but caution should still be exercised for areas of the mouth requiring heavy function. Continuing research is exploring the significant vulnerabilities of the porcelain systems in such areas.
